Abstract: According to the double redundancy and light weight requirement of aerocraft ,designed concentric magnetic road annulate transformer  high reliability and high precision double redundancy brushless dual speed resolver. The problem which is on designing concentric magnetic road redundancy brushless dual speed resolver has been solved successfully by reasonable designing of the resolver ,such as electromagnetism and structure , the finite element theory to electromagnetism.The experiment results show that resolver designed by the method satisfies the requirement of design,has high performance with intensive engineering application value.
Key words: resolver； double redundancy
